Summary:To provide an organic electroluminescence element and use thereof.SOLUTION: An organic electroluminescence element includes a metal complex which has a substituent group A capable of reducing maximum capacitance of the element, and the metal complex is usable as a light emitting material of a light emitting layer of the electroluminescence element. The element including the metal complex having the substituent group A can reduce the maximum capacitance of the element to improve a response time and a refresh frequency when an OLED display element has low gradations. The substituent group A, on the other hand, can reduce the maximum capacitance of the element. Simultaneously, the element manufactured with the metal complex including the substituent group A can still maintain its superior performance as compared with an element manufactured with a metal complex not including the substituent group A. According to the present invention, there is further disclosed an electronic assembly including the organic electroluminescence element.SELECTED DRAWING: Figure 1 【課題】本発明は、有機エレクトロルミネッセンス素子及びその使用を開示する。【解決手段】本発明に係る有機エレクトロルミネッセンス素子は、置換基Aを有し且つ置換基Aが素子において最大静電容量を低下可能である金属錯体を含み、金属錯体は、エレクトロルミネッセンス素子の発光層における発光材料として用いられることができる。置換基Aを有する金属錯体を含む素子は、素子の最大静電容量の低下をもたらすことができることで、OLED表示素子の低階調時における応答時間およびリフレッシュ周波数を向上させることができる。一方、置換基Aは、素子の最大静電容量の低下をもたらすことができる。それと同時に、置換基Aを含む金属錯体により製造された素子は、置換基Aを含まない金属錯体により製造された素子に対して、優れた素子の性能を依然として維持することができる。本発明は、有機エレクトロルミネッセンス素子を含む電子アセンブリをさらに開示する。【選択図】図1
